' JACK STAND.

Application area Jury si,

To @ZZ whom t may concern.'

Be it known that T'"ILLIAM andEDrroND HALL BECKER, citizens of the United States, residing at Mexia, in the county of Limestone and State of rexas, have invented certain new and useful Improvements in J ack Stands, of which the following'is a specification.

This invention relates to improvements in jack stands such as are employed in the operation of re-brassing railway car ournal boxes, and the object of the invention is to provide a jack stand embodying means for holding the car wheel upon the rail and thus prevent the wheel being lifted with the journalr box when the jack is operated to elevate the said box.

More specifically, it is another object of the invention to provide, in a jack stand of this type, a novel construction of means for engaging the car wheel, which means maybe readily applied to thel wheel and be securely anchored thereon without the employment of extraneous fastening devices, so 'that with the expenditure of but little time and labor the device may be securely anchored in place.

Another object of the invention is to. so construct the anchoring means for the wheel that the same may be engaged with wheels of various diameters.

In the accompanying drawings:

Figure l is a 'perspective view of the jack stand embodying the invention arranged in position for use, the jack to be employed in connection therewith, being emitted from the figure in order to better illustrate the actual invention Figure Q, is a vertical longitudinal sectional view through the base of the jack stand and illustrating in elevation one of the anchoring devices constituting a part thereof;

Figure is a vertical front to rear sectional view through the wheel engaging and anchoring member of the device.

In the drawings,` the reference letter XV indicates a railway car wheel which is to be held to its position upon the rail R at the time the jack (not shown) is being employed to elevate the journal box indicated by the reference letter J. The device embodying the invention comprises a base which is indicated in general by the reference numeral l and which may comprise a flat plate either cast or otherwise formed, the plate being provided upon its uppervside with lan annular upstanding flange 2 constituting a seat Moon Banny.

3 for the base of the lifting jack (not shown) set screws t being threaded through opposite sic es ofV the ange 2 and being designed to be tightened to bind the base of the jack and thus secure the jack in'position upon the base l, and retain the same against displacement.

At one end the base plate is formed with a longitudinal extension 5 which is designed to ex end beneath the rail R at a point likewise beneath the wheel `W which isto be held to the rail during the jacking operation. At opposite sides of the extension 5, the base plat-e l is provided with ears or bracket portions G which occupy preferably a. vertical plane andvwhich extend upwardly beside the outer side of the rail R, when the base is placed in position as illustrated in Figure l of the drawings. A short length of chain, indicated by the numeral 7, is permanently connected at one end to the upper end of each of the bracket members 6, and a hook 8 is connected permanently to the other end of the said chain.

The car wheel engaging and anchoring member of the device is indicated in general by the numeral 9 and the said device preferably comprises `a frame formed from heavy rodmaterial, the frame including a front bar l0, a, rear bar l1 extending parallel thereto, and side members l2 which connect the corresponding ends of the front and rear bars. vSubstantially at their juncture with the ends of the front cross bar l0, the side members 12 are each provided with downwardly extending bends 13 which are open at their upper' sides and in which rest the uppermost links Ac of chains 15 which chains are thus suspended in depending relation from the frame 9, the corresponding hooks 8 upon the chains 7 being interchangeably engageable with the links of the chains 15 so as to connect the anchoring men'iber 9 with the base of the device. In order to prevent twisting of the chains l5, swivels 1G are interposed in the said` chains at' any suitable point inI their length, as, for example, adjacent the uppermost link 14. At this point it will be understood that regardless of the diameter ofthe wheel W, the chains l5 may be adjustably engaged with the hooks 8 so as to extend substantially taut between the anchoring frame 9 and the base of the device.

The intermediate portions of the side members l2 of they anchoring frame 9 are designed to extend across the tread of the car cross member ll of the frame extends across the inner side of the said wheel. l

Having assembled the supports with the wheel and rail in the manner above outlined, and with the chains 15 extending downwardly at opposite sides ofthe journal box J, the ordinary lifting ack is mounted upon the base l within the seat 3 and secured in place by the set screws 4, the head of the jack engaging beneath the journal box J; The jack may then be operated so as to elevate the our-nal box and in this operation the downward pull exerted upon the chains l5 and the anchoring frame 9 will serve to hold the wheel W7 firmly to the rail R andr prevent the wheel being lifted with the journal box. As a consequence, when the journal box has been sufiiciently elevated, the brass may be readily removed therefrom and a new brass substituted therefor.

Having thus described the invention, what is claimed as new is:

1. A lifting jack stand of the class described comprising a jack supporting base,

having a portion to engage beneath a rail and upstanding ears at opposite sides thereof and adapted to bear against the base of the rail, hooks c-onnected to the; said ears', an anchoring frame formed to seat over the upper. side of a car wheel, and flexible connecting elements extending from the frame and connected with the said hooks.

2. A lifting jack stand of the class described comprising a jack supporting base having an upstanding continuous flange providing a seat for the base of a jack, a set screw adjustably threaded through the said fiange to engage and anchor the said base of the jack, an anchoring'member formed to seat over the upper side of a car wheel, and flexible connecting elements depending from the anchoring member and connected with the base.

3. A lifting jack stand of the class described comprising a supporting base having a reduced extension adapted to fit beneath a rail and provided at opposite sides of said extension with upstanding attaching ears, an upstanding seating flange carried by the supporting base in advance of the ears, means carried by the flange for engagement with ajack, an anchoring mem-, ber adapted to fit over the top of a car wheel, and flexibleconnecting elements depending from the anchoring member and connected with the ears.

In testimony whereof We affix our signatures.
